Robb Godshaw is an industrial design student at R.I.T., and he's come up with a strange and brilliant invention: The Cryoscope Haptic Weathervane, which is essentially a tactile temperature indicator. Touch it and you can feel what the temperature is outside.
The Cryoscope is equipped with a heat sink, a thermoelectric-cooling Peltier element, and a cooling fan, all combined and operated by an Arduino controller that receives forecast data from a Web-based app, all neatly enclosed in an aluminium cube ready to be touched.
You might think "Why would someone need this?" I totally need this: I live in windowless apartment with a deceptively drafty interior. I literally have to go downstairs and outside of my building to see how hot or cold it is outside and if it's raining or not.
Sadly, Godshaw's project, though it appears to work, will apparently remain in the concept stage, with no plans for production.
